Driven by demand for higher speed fiber cables, network cabling has gone through great changes over the years. Cat5e copper cabling and 1000BASE-T have dominated data center interconnection application for years. However, SFP cable becomes a new favorite with less cost and lower power consumption, which is a form of the high-speed cable with pluggable on either end. This direct attach cable…

The 10G transceiver is considered as the mainstream module in the market due to its mature technology and low price. There are various types of 10G transceiver modules like 10GBASE SR, 10GBASE LR, etc. SFP-10G-SR and X2-10G-SR are two very popular 10GBASE SR optical transceivers, which offer customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and…

The optical transceiver is one of the most important elements in data centers. Currently, QSFP28 transceiver module is the leading product on the market that supports 40 and 100 Gigabit Ethernet application. However, the world is constantly changing and evolving, new applications such as 4K HD video, webcast, VR and cloud computing have driven a sharp growth of network traffic. Therefore, today, QSFP56 and…

In current optical communication market, optical transceiver products are developed in the trend of high data transmission rate, longer reaches, lower power consumption, etc. To keep pace with the trend better, many new optical module products with high transmission rate and longer reaches emerge, such as the latest one, QSFP28 4WDM(4-wavelength Wavelength Division Multiplexing) optical transceiver. In this article, we…

With the upgrade of the network from 10G/25G to 100G, 100G Ethernet begins to prevail in the optical communication industry. After that, various solutions appear for 100G Ethernet, in which CFP series and QSFP28 series optical transceiver are regarded as the two main solutions. However, by comparison, QSFP28 series is seemingly preferred by most data center users for the upgrade…

On account of higher requirements for transmission rate and transmission distance in current optical interconnect markets, QSFP28 optical modules appear for options. QSFP28 optics consist of QSFP28 100GBASE-CWDM4, QSFP28 100GBASE-PSM4, QSFP28 100GBASE-SR4, QSFP28 100GBASE-LR4, QSFP28 CLR4 and etc, among of which QSFP28 CWDM4 and QSFP28 CLR4 are the most suitable solutions for one who demands long distance, high transmission rate,…
